Company Experience 18 - Manuela Cortés Granados's CV

At Hardnetics (Oracle Partner), I served as an Oracle Service Bus Developer, where I gained hands-on experience building and optimizing highly scalable middleware solutions designed to support large-scale enterprise applications under heavy load. Working with Oracle Fusion Middleware 12c and OSB 12c, I engineered robust OSB Proxy services and complex JSON-to-XML data transformations that enabled seamless backend integrations for Claro, a major telecom provider handling massive volumes of concurrent requests daily 📈. I implemented dynamic authentication workflows and business rule–driven routing, ensuring secure and efficient processing in a high-traffic environment, crucial for maintaining performance and reliability when scaling to tens or hundreds of thousands of users 🔐⚙️. My role involved performance optimization and scalability tuning of middleware services to support enterprise-grade applications requiring high availability and responsiveness, directly aligning with the need to manage backend systems under heavy traffic and concurrency pressure 🚀. This experience equipped me to handle backend challenges in applications serving large user bases, providing the stability and efficiency essential for high-demand environments, even though the focus was on middleware rather than frontend development.
